3/21 · that are only slightly above the target size for the flotation feed, which would typically be in the 100 um to 200 um range. This is usually caused by poor control of the grinding process or deficiencies in hydrocyclone classification. The first challenge of very coarse

Improve the stability of the grinding (SAG / Ball Mills) and flotation plant (conventional and Jameson cells), through improved instrumentation and control strategies. Mipac scope: Design, specification, configuration and commissioning of full plant-wide control system for the upgraded smelter.

Each milling circuit is unique, and as such the goals and most optimal control strategy might differ for individual cases. Process IQ is an expert in implementing control systems for SAG and Ball milling circuits, making use of advanced stabilisation and optimisation strategies developed by Mintek.

The Improvement Effect of Dispersant in Fluorite Flotation . At present, we commonly adopt the flotation method to remove the mineral impurities except fluorite in the fluorite ore to improve the content of CaF 2, among which the dispersion process is a very important technique and the selection of dispersants will have a direct impact on the contents of CaF 2 of the final products In this
